# ELF-010 — Power-frequency brain DNA response and chemical interventions

Why this matters
The abstract reports DNA strand breaks in rat brain cells after prolonged power-frequency magnetic-field exposure, with several chemical interventions blocking the response. It suggests a pathway to test, rather than a settled explanation of harm. Full methods and independent replication remain to be assessed, separately from radiofrequency studies.

Topic: Power frequency fields

Verification Group: Original abstract verified

Record Role: Original abstract verified methods pending

Featured: False

Exposure: 60 Hz magnetic field at 0.01 mT for 24 or 48 h; additional acute experiments described in original abstract.

Design: Rat-brain assays with antioxidant, nitric-oxide-synthase inhibitor and iron-chelator interventions; exact n and full methods pending.

Finding: Original abstract reports strand-break increases after 24 h, larger after 48 h, blocked by Trolox, 7-nitroindazole and deferiprone; apoptosis/necrosis also reported in acute experiments.

Boundary: Power-frequency experiment, distinct from GHz RF. Interventions support hypotheses, not a settled general mechanism; full methods/replication audit incomplete.

Related: Same Washington investigators as RF-050 and RF-051; different field regime.

Protection Question: Do the chemical interventions identify a reproducible pathway for the reported DNA response? Abstract-only verification and incomplete replication checks leave that mechanism provisional and separate from GHz RF evidence.
